This is a powerful step, with which you can accomplish multiple commands. Please read about the shell command in Unix or Windows before using this.

For Windows: to be able to use spaces and quotes in the command wrap the whole command in 2 extra double quotes, one at the beginning and one at the end, like “”C:\testapp.exe” “test param””

(Windows) If you choose UTF8 Encoding the plug-in indicates invalid UTF-8 characters with the string <INVALID UTF8>.


On Windows:

Execute Shell [ Select ; gResult ; "dir C:\"  ]

On Mac OS:

Execute Shell [ Select ; gResult  ; "ls /" ]

This will list the contents of the root folder.

Example 2

On Windows:

Execute Shell  [ Select ; gResult ;  "echo testtext > C:\example.txt" ;  Timeout: 5  ]

On Mac OS:

Execute Shell  [ Select ; gResult ; "echo testtext > /example.txt" ;  Timeout: 5  ]

This will create a text file example.txt on your startup disk. If the command takes more time than 5 seconds the plug-in will return with a timeout error $$-4230.
